I just made it out of the garage - been in there two days I think
First an appology the bearing I showed was in fact 64> Ford Truck, also for an earlier ford car.
I just pulled one off a 52 trans side shift, Daves old one - The bearing+Hub is 1.5 in front to rear measured thru the bearing/hub center
Pictures to come later along with some PN info.

Dick, the first picture you posted on this page shows your clutch disc on the input shaft. It looks to be a good 1/4 to 3/8 of the input shaft sticking through the clutch disc hub. When I had my 11" disc on your old trans the end of the clutch hub was even. Not sure what page its on but there are pictures posted.
If you look at the 2 ross just posted you can see there is about a .390 difference in thickness of clutch disc hubs, the 11" being thicker. I think this is why my disc wouldnt disengage from the flywheel.
Not sure how or why my old 3 speed column shift worked with an 11" clutch

Hold on to that 11" clutch disk - I would think that there is more to the mystery than just the thickness - Possibly that is a disk for another vehicle - Everything that I have seen shows the 9" thru 11 " disks as interchangeable as long as it matches the input shaft diameter

Ok, I will hold onto it. It definately matches the input shaft diameter. Let me know what you find out.
I am going to install the 10" this weekend and see if that works.
If the 11" disc is wrong that would expalin why my original trans worked with an 11" disc

It is very possible that when these parts were being built that a hub assembly for a Studebaker/dodge/? got mixed in the Ford bin
There is only so much space between the flywheel and the back of the input shaft - If the clutches are interchangeable the clutch disk/pressure plate/throwout bearing all have to be equal

UPDATE...The clutch disc disengages and the truck rolls completely free while in gear with the clutch pedal pushed in.
I got my 10" clutch in the mail and of course the pressure plate doesnt line up with any of the bolt holes in my flywheel. My flywheel is drilled for the 10 and 11 inch clutch but the 10 inch set of holes was a little off.
I called the machine shop and asked them if they wanted to redrill the flywheel or machine the hub of the 11 inch clutch disc to match the dimesnsions of the 10 inch clutch disc. He suggested using the 11 inch pressure plate with the 10 inch disc. I didnt think that was possible but he said as long as all of the friction material from the disc was engaging with 100% of the pressure plate I would be fine.
Havent road tested the truck yet but across the garage floor it moves and coasts as it should.
Fixed that only to discover my next problem.
New carb from advance auto leaks gas on the passenger side near where there is a tube that goes up into the carb by the choke linkage. Accelerator pump rod maybe? Id this an easy fix or should I just return it for a new one?

They were 3 groups of 2, however the holes in the flywheel were off by half a bolt hole. I could have drilled all 6 holes of the pressure plate 2 sizes bigger each and it would have fit just fine. I just didnt want to get it "close"

Don't be drilling out the holes in the PP they need to be sized to match the recessed holes in the flywheel . Your machinist is correct about using dissimilar disc and PP sizes as long as all the friction material is covered .
